Answer:
the answer is a where x=8
Explanation:
cross multiplication method
Answer:
Step-by-step explanation:
okay don't feel bad, you actually got it right, let me help you with some holes!
You calculate slope by the rise over run. These people are confusing you a bit - do problem 2 then 1
the vertical change is -1 horizontal change is 3 so by rise/run=-1/3
-1/3 is the slope
for the second problem this is confusing but just read and try to analyze
vertical change/horizontal change = 5-4/0-3= 1/-3(or -1/3)
The y intercept is the point where the line hits the y axis, so at point (0, 5)
The function is y=mx+b
m is the slope
b is the y intercept
so y=-1/3x+5
Answer:
2.56
Step-by-step explanation:
The equation they dive u: d = 16t^2, so in the question they said what's the distance, d, if t = 0.4
So you just have to replace t with 0.4:
d = 16t^2
d = 16(0.4)^2
d = 16(0.16)
d = 2.56
Answer:
D). irrational numbers
Step-by-step explanation:
The irrational numbers are the set of number which can NOT be written as a ratio (fraction). Decimals which never end nor repeat are irrational numbers. Irrational numbers are "not closed" under addition, subtraction, multiplication or division.
Answer:
Step-by-step explanation:
Givens
d = 2365 miles
r = 55 miles / hour
t = ?
Formula
d = r * t
Solution
d = r * t
2365 = 55 * t Divide by 55
2365/55 = t
t = 43 hours.
